question about cdi-450 w/vcd(22er9956)adapter compatability.

ok i have a cdi-450 with the vcd adapter and i was wondering can you use any disc that says its vcd compatable on this
unit? asking as i have found but not picked up yet a disc that says its vcd compatable on it and has(i think) the columbia
tristar logo as well as says made by sony, im going on memory as i didnt have time look more closer( im guessing that this is a movie preview/demo disc. any input would be grateful thanks.
